For the most part, this was all what I did: # freebsd-update -r 11.2-RELEASE upgrade # freebsd-update install # reboot # freebsd-update install After it’s been upgraded, I also need to update the Zpool. root@nas:~ # zpool status pool: zroot state: ONLINE status: Some supported features are not enabled on the pool.
